According to The Information, Microsoft wants to bid to make Bing Firefox’s default search engine. Android Police reports:
The browser’s contract with Google is set to expire this year, at which point Mozilla could either renew it or switch to a different search engine. Microsoft would very much like to take Google’s place in Firefox. It’s not a guarantee that it will actually help boost Bing’s usage — after all, Firefox users who don’t want to use Bing could just switch to a different search engine, as Yahoo found out a few years ago — but Microsoft sees potential in such a deal.
The report also notes that there’s also a potentially more juicy opportunity coming up for Microsoft if it really wants to get serious about pushing Bing. Apple’s Safari browser, which is the main web browser on Apple devices, will have its Google contract expire next year. Despite throwing shade constantly, Google really benefits from the deal it currently has with Apple, and Microsoft could sweep in and try to get Bing to become the main browser on iPhones.
